Specificationof To all whom it may concern: 1 t

-Be it known that L SAMUEL Snvnnson, a citizen of the United States,and. resident of Valders in the county of Manitcwocand State ofWisconsin, have inventedfcertain new and useful Improvements inHair-Cutting Appliances; and 1 do hereby declare that the following is afull, clear, and exact description thereof.

My. invention relates to new and useful improvements in hair cuttingappliances'of that type in which the cutters are mechanically operated.v s

It is in general the object of this invention to rovide a very. simplyconstructed and rea ily manipulated hair cutting appliance which iscapable of trimming hair to any desired length and for cutting anylength of hair with great facility.

I-t'is also an object of the invention to provide a device ofthischaracter having cutting members Which can be automatically shiftedto cut hair oftdiiferent lengths, or which can be retained stationary totrim hair of the samelength. f i

Still another-object of the invention is to provide an appliance of thisnature having means for evenly. drawing; the hair to be out into rangeof the cutting members. I

With these general objects inview the invention consists in the novelfeatures of construction, combination and arrangement of parts whichwill be hereinafter more particularly described and claimed. I

In theaccompanying drawing: to

Figure 1 represents a longitudinal sectional View taken substantiallyonthe plane .of the line 1 1, of Figure 2.

Figure 2 is a part side elevational and part sectional view of theappliance.

Figure 8 is a transverse sectional view through the gear h0using, and

Figure i is a similar sectional view taken on the plane of the line 44of Figure 2.

In the preferred embodiment of the invention as illustrated in thisdrawing, the reference character 1 denotes an elongated sub stantiallyrectangular casing, open at both ends and having its sidewalls at itsintake end extending beyond the adjacent edges of the other walls toprovide spacing fingers 2. Theoppoiste end of the casing is closed by aremovable cover 3 secured thereto by screws or the like 4. The cuttercomprises a carrying plate 5 slidable in the casing 1. and engaging theinner surface of the several walls thereof, a relatively stationarycutter n: Patented July is, race.

bar 6, and a reciprocable cutter bar As is customary in this type ofcutteuthe bars 6 and 7 are provided along one longitudinal edgewith"co-operating' cutter teeth 8 and 9, the flatter being shifted intoand out of alinement with the teeth 8, upon reciproca tion of the cutterbar 7. The last mentioned cutter bar is disposed between the carryingplate 5 and the stationary cutter bar 6 itbeingheld in operativeposition with respect thereto by retaining bolts 10, the

same extending, transversely through the several parts of the cuttingmember and hav mg nuts 11 on their threaded ends. Springs 12 arelocatedbetween the carrying plate 5 and the inutsll to. procure ayieldableo enj gageinent betweenlthe ,cutter bars and the plate Thecarryingplate 5 also provides a hearing 13 for one endvof a feedshaftl iwhich extends longitudinally through the casing l and has an eccentric15 at one end 'dlSPOSGCl in an opening in he cutter barq.

Thus rotationof. the shaft 14 turns the eecentric and reciprocatesthebar '7, this being permitted in view' 'of the bolts 10 being disposedin the slots 10. o f H The end portion ofthe feed shaft l l 0pposite theend carrying the eccentric 15 is rotatably journaled in the cover Sandisv slidahle' longitudinally through the hub 16 of a WOIIl'l gear--17,the sameobeing splined thereto by means of a-f'eather and the key groove18. y The worm gear 17 is rotatedby means of a, worm 19 formed on thestub shaft 20; the latter extendingtransverselyof the casing 1;andhavinga suitable flexible shaft 21 1 connected thereto forrotationfrom a suitable source of power. The hub 16-of the worm gearlisjournaled in a bearing carried by a wall'92 which partially defines agear housing 23, one side ofsaid housing being closed bv said rover 8andtwo'of the other sides by the walls of the casing 1.

i From this construction it will be seen that rotation of the stub shaft20 causes the feed snaft i lto be revolved with a. consequentactuationnf the cutter bar'T. The rotation of the feed shaft 14: isusedfor movmg 1 so as to shift the cutter member inng the parts the gearhousing23' contains a slidable feed plate'24, o. e end of which isbifurcated and hasthe shaft 14 disposedbetween itsfurca tions andadapted to he engaged by a thread portion 26 at the will of theoperator;

5., 6 7. In other words the sane longitudinally through the ca Theopposite or outer end of the plate 241. extends through an opening inthe casing 1 and is bent laterally to provide a finger piece 27. Anexpanding leaf spring 28 located between the finger piece and the adjacent wall of the casing 1 normally urges the teed plate outwardly todisengage the thread portion 26 from the threads of the feed sha'it l l.During such disengagement the shaft 14 merely rotates and the cuttermember is held against shitting longitudinally of said casing. On theother hand, as soon as the operator forces the thread aortion 26 intoengagementwyith the threas of the shaft 14, the rotation of the lattercauses the same to be fed outwardly of the casing. In Figures 1 and 2the shaft has been partially fed from, the casing to space the cuttermember inwardly otthe intake end of the latte: r. ;ks shown in Figure 1the feed plate 24: is slidable in guides 29 carried by the cover 3. i p

The casing 1 adjacent the closed end thereof is provided with a suctiontube attaching nipple 30 whereby the interior-t the easing may besubjected to the action of a suitable vacuum mechanism (not shown.) Thatis to say by such an arrangement air is drawn through thecasing from theopen end thereoi and through the cutter member. In order that this airmay be drawn transversely across the cutter bars throughout the lengththereof, the carrying plate 5. is formed with a longitudinally extendingintermediately located suction slot 31. This slot is positioned inwardlyof the innerends of the teeth 8 and 9 so that the air entering thecasing 1 is deflected with a result that the hair. is positively drawnthroughthe teeth 8 and 9. As indicated at 32 the portion of the carryingplate adjacent the teeth 9 is cut away to'readily permit said hair toenter the slot 31. The carrying plate 5 also has friction elements 33,disposed in its ends for engagement \viththe side walls of the casing 1.such an arrangement being conducive to a more eflicient operation.

In the use of my. invention, the operator starts the rotation of theworm shaft the same being connected to the flexible shatt of saidsuitable source of power, whereupon the cutter will reciprocatecontinuously, If short hair is to be cut, the cutter member is locatedat the extreme open end ot the casing 1 between the lingers 2, and as itis desired to cut less and less hair, the cutter member is progressivelymoved into the casing merely by pressing upon he finger piece 27.However, ita particular length of hair is desired, the cutter member ismoved into the casing a suitable distance and permitted to operate inthis position as long as necessary, the feed plate 24: under suchconditions being inactive.

Although the the invention is above described,

preferred embodiment of shown in the drawing and it is to be understoodthat various changes may be madein the difi erent parts of the applianceand in the proportions or its parts, withoiit departing from theprinciples or sacrificing any of the advantages thereof.
